HINGE.

Specification of Letters Patent.

Patented Jan. 11, 1916.

Application filed October 27, 1915. Serial No. 58,153.

To all whom it may concern Be it known that I, STEPHAN BOHNERT, a subject of the Emperor of Austria-Hungary, residing at Cleveland, in the county of Uuyahoga and State of Ohio, have invented certain new and useful Improvements in Hinges, of which the following'is a specification.

This invention relates to hinges and particularly to hinges suitable for use with table leaves and under other conditions where it is desirable to have a hinge which is flush with the surfaces to which it is applied, so that when opened the top will be entirely fiat, and which when closed will be concealed and will hold the surfaces out of contact with each other at the hinge connection.

A further object of the invention is to provide an improved hinge of this type which will be strong and rigid, and easily assembled.

In the accompanying drawings-Figure l is a front elevation of part of a sewing machine table provided With the hinge. Fig. 2 is a perspective of a part of the hinge. Fig. 3 is an end view of the connecting members or links between the hinge leaves, in open position. Fig. 4 is a similar view of the parts in closed position. Fig. 5 is a top plan of said parts. Fig. 6 is a top plan view of the hinge, open. Fig. 7 is a side view thereof, closed. Fig. 8 is a section on the line 88 of Fig. 6. Fig. 9 is a similar view, with the hinge closed. Fig. 10 is a perspective of one of the hinge leaves.

Referring specifically to the drawings, 6 indicates the standing part or table top to which the swinging part or table leaf 7 is hinged.

The hinge comprises two similar leaves or plates 8, which are flat, and adapted to be set into the surfaces of the parts to be connected, and fastened by screws 9 through holes 10, and preferably flush with the surfaces. Each leaf has at one end thereof a marginal tongue 11, bent over parallel to the leaf, on the inner side thereof, and adjacent each of these tongues is an eye 12 formed by bending another tongue to circu lar form. A space 12 is produced between each pair of eyes 12, and receives the connecting links or members. A plurality of these links or members are emploved, divided into two sets. each setconsisting of a number of plates 13 with convex outer edges as indicated 141 and with notched inner edges as shown at 15. These two sets of plates are connectedin alternate or inter- .leavedrelation by means of a pivot pin-16, so that they are free to work on or beside '17 which projects into the eyes 12 of the hinge leaf, at each end, and when the hinge is closed these pintles are received or swing into the notches 15 which are in alinemcnt across each set. At the end opposite the pintle 17 the members of each set are connected by a pin 18, the ends of which are flattened as indicated at 19, and these fiattened ends are slidable or movable laterally in guides formed by the tongues 11 of the leaves. The members of the respective sets cross each other, and each set is connected at one end by the pintle 17 to one leaf, and lzlit ghe other end by the pin 18 to the other When the hinge is opened, as shown in Fig. 3, the pins 18 and their flattened ends 19 slide outwardly in the guides under the tongues 11, until the parts 6 and 7 stop or abut against each other, at which time, also, the knuckles of the leaves 8 come together, and assist in supporting any weight on the hinge. WVhen the hinge is closed, as shown in Fig. 4, the pins 18 at first have a sliding movement inwardly under the tongues 11, incident to the different axes of movement on the pintles 17, the pivot 16 approaching or being moved toward a line between said pintles, and on further closing movement the pins 18 again move or slide inwardly under the tongues 11 until the pintles 17 strike or stop against the inner ends of the notches 15, as shown in Fig. 1. This action produces an extension or spreading of the leaves, so that they are opened up or lifted apart and do not contact with each other, whereby the table leaf 7 is held out of contact with the top 6, as shown in Fig. 9. The leaf and top are mortised as shown at 20 to receive the sets of connecting members on the inner or under sides of the hinge leaves.

The hinge is quite easily assembled. the leaves being first produced. and the connecting members assembled therewith bv placing the same in the recesses 12 and inserting the pintles 17.

What I claim is:

1. A hinge comprising two leaves. each leaf having a pair of eyes and a pair of tongues bent to form guideways, sets of connecting members pivoted together and to the eyes of either leaf, and a pin extending through the members of each set and having flattened end portions slidable in said guide- Ways.

2. A hinge comprising two leaves, each leaf having a pair of tongues bent inwardly at the ends of the leaves to form guidevvays, and sets of connecting links pivoted together and to either leaf and having projections slidable in saidguideways. 3. A hinge comprising two leaf plates having eyes at their adjacent ends and also tongues at said ends bent backwardly to form guideways between said tongues and the plates, sets of conneotlng members pivoted together and to the eyes of either leaf,
